2.2.5    Phase 6: Options Assessment
         There are numerous adaptation options that may be considered for mitigating risks from coastal
         hazards in the Noosa area. The adaptation option hierarchy adopted for the CHAP generally aligns
         with that adopted for the Noosa Environment Strategy (2019), which is shown in Figure 2-1.


                                                            Measures are implemented to ensure a 'no
